A precise sequence of left-right asymmetries, combined with mechanical constraints, is sufficient to drive the looped morphogenesis of the embryonic heart tube, with potential impact for congenital heart defects.

The somatosensory cortex doesn't integrate mixed bilateral inputs, as partially uncrossing projections from the whiskers duplicates their representation by segregating lateralized inputs from each side of the head.

The organization of layered/laminated axon projections in specific regions of the fruitfly central brain is regulated by short-range repulsive guidance and is critical for local inhibitory circuit formation and function.
